We've been waiting for SiliconDust's CableCARD-compatible HDHomeRun Prime for a little over a year and it seems finally ready to bring its triple tuner TV magic home, having gained CableLabs certification as of April 28th and subsequently showing up for preorder on Amazon. While this is mostly big news for Windows Media Center fans who need a new way to get premium channels on their box it also supports other DVR software like MythTV on Copy Freely-marked content. HTPC builders don't have to choose between this HDHR3-CC and the (suddenly in abundant supply and still $399) Ceton InfiniTV 4 just yet, since the listing has no shipping date and the last we'd heard from SiliconDust was that preorders would ship around 30 days after it completed certification. Check out our hands-on impressions from CES a few months ago if you're on the fence, but right now all that's standing between you and that grey box is a little bit of time... and $207.

Update: According to a post on its forum, SiliconDust confirmed the HDHomeRun Prime has been certified and an email announcement will follow shortly, however it expects to deliver a 6-tuner Theater version first with the three tuner box appearing afterwards. The post also notes sites are "incorrectly listing" the HDHomeRun Prime for preorder and "will not be first in line for delivering product" so you may want to wait for the official word on which "major retailer" has the go-ahead to make sure you're first in line. The option to preorder disappeared from Amazon this morning, we'll let you know when and where the option to purchase pops up next. [Thanks, robniep]
